1,126,391. 7 Specification of Letters Patent Patented J an. 28, 11915.

Application filed May 20, 1914. Serial No. 839,861.

To all whom it may concern 7 Be it known that I, Ancns'rm J.Guevar'r'ra, a citizen of the United States, residing at \Vorcester, inthe county of \Vorcesshuttle box.

It is the object of my invention to provide an improved construction indevices of this character, combinmg efliciency of ally mounted at 16upon av bracket secured to the lay 10. The stud 17 which constitutes apart of the ball-and-socket connection 14 is threaded and is providedwith nuts 18 by which the relation of the binder to the arm may bevaried. The other end of the lever 15 comprises a substantiallysemicircular arm 15", formed integral with the arm 15 the outerextremity by the arm 15* being positioned at the rear of the lay. Thearm 15" is connected by toggle links 20 and 21 .to a stud 22 fixed inthe lay. The link 21 is provided with a rearwardly extending arm 23positioned to contact with the end 15 operation with simplicity of partsand econof a sliding rod 21. Y

Having thus described my invention it will be evident that changes andmodifications can be made therein Without departing from the spirit andscope of the invention as expressed in the claims, and I do not Wish tobe limited to the specific details herein disclosed, but

What I do claim is 1. In a loom, in combination, a lay, op erating meanstherefor, a binder on said lay, a lever mounted on said lay andpivotally connected to said binder, means to positively lock said leveragainst the outward pressure of said binder, and connections from saidoperating means to said locking means, whereby said locking means isalternately moved into and out of locking position.

to one end of said lever, a toggle connected to the other end of saidlever and to the lay, yielding means for closing said toggle, andpositive means for breaking said toggle.

4. In a loom, in combination, a crank arm, a binder, a lever adjustablyconnected to said binder, a substantially semi-circular arm integralwith said lever, toggle links pivoted to the end of said arm and to thelay, yielding means for closing said toggle, and means positivelyactuated by the crank arm to open said toggle.

5. In a loom, in combination, a binder, a

lever adjustably connected to movably support one end of said binder,said binder being free to rock in any direction on said lever, and meansto periodically and positively lock said lever against outward pressureof said binder.

In testimony whereof I have hereunto set my hand, in the presence of twosubscribing witnesses.
